GANG-DRAWER FASTENING OR LOCK.

SPECIFICATION forming part of Letters Patent No. 339,486, dated April 6,1886.

Application filed December 23, 1885. Serial No. 186,580. (No model.)

To all whom it may concern:

Be it known that I, SUMNER SHAW, of Boston, in the county of Suffolk andState of Massachusetts, have invented a new and useful Improvement inGang-Drawer Fastenings or Locks, of which the following is a specilication.

Hy invention appertains to the class of locking devices, applied to aseries of drawers or compartments, customarily designated as gaug-lochs;and it consists in an original and ingenious arrangement of mechanicaldevices, whereby one or several receptacles may be simultaneously lookedthrough the action of one key. The construction of said mechanism andthe operation of its parts is clearly illustrated in the drawings,forming a part of this specification, in which Figure 1 is a rearelevation of a bureau with a portion of the back removed to expose theapplication of my improved device. Fig. 2 indicates an end elevation intransverse section on line :r, Fig. 1, to exhibit the position of thekey and rotating locking-lever. Fig. 3 exhibits in perspective a drawer,to show the position and manner of applying the drawercatch. Fig. 4 is afront elevation of my gang-drawer fastening, illustratinga modifiedconstruction as applied to massive receptacles.

The utility of my improved invention is further exemplified in theseveral views thereof, wherein similar letters of reference indicatelike parts, referring to which- A indicates the bureau, and B B thedrawers therein. 0 G are the runs upon which said drawers rest and slideand through which the opening is formed to admit the key (1.

D D exhibit the drawercatch, the unattached end of which is offset fromthe plane of its attached surface to permit the entrance of theprojecting arms E E of the vertical sliding locking-bar F, which isattached by two or more swing -straps, G G, one end of which, H, ispivoted to said sliding-bar F,while the remaining end, I, is pivoted ina like manner to the bar J, which is immovably secured to the back ofthe receptacle containing the drawers to be locked. In thelighterarticles of furniture manufactured, said sliding locking-bar F isattached to the immovable bar J,

by the rotating locking-key lever L, Fig; 2, whose end is refiexed at aright angle, as at K, Fig. 1, pivoted to the lower end of the of thereceptacle immediately above said bar,

sustains the same when it is elevated and in a position to secure thedrawers, as indicated by the dotted lines, Fi 1.

In the heavier articles of manufacture I adapt the modified constructiondelineated in Fig. 4, wherein the locking-bar is confined by and movesvertically within two or more fixed straps, I, and is provided upon oneedge with a rack, Q, which engages with a segmental gear, R, whichlatter is actuated by the rockerlever L, to release or secure thedrawers, in the manner previously described. It will be obvious thatsaid lever L may be placed at any height convenient to the user, andthat alternate drawers, or one to the exclusion of others, may be leftunsecured by sliding the drawer slightly forward, when the verticalmovement of the projecting arms E E will escape the catch D on the same.Greater secnrity is also attained in the position of the key andlockinglever, as the unity of these parts is placed so far within thefront of the receptacle as to render tampering with the locking-leverimpracticable.

The operation and construction of my improved invention having beendescribed, I desire to secure by Letters Patent and claim- In agangdrawer-fastening device simultaneously fastening a series ofreceptacles, the stationary bar J, bearing supporting swingstraps G G,the vertically-sliding locking'bar F, having projecting arms E E andprojecting lip N, combined to operate with the ellipticalsupportingcatch 0, the drawcatch D, and actuating-lever L, with therefiexed arm K, substantially as and for the purpose herein specified.

In witness whereof I have signed this specification in presence of twosubscribing wit nesses.

SUMNER SHAXV.
